SCTX2B

：0755-61169046 QQ635222749 SCTX2B/SDRX2BD (NO：S&CIC0515) FIVE FUNCTIONS REMOTE CONTROLLER Features     Wide operating SCTX2B voltage range: 2.4V to 12V SCTX2B very low stand-by current Few external components needed SDRX2BD built- in 3.8v zener General Description The SCTX2B/RX2BD are a pair of CMOS LSIs designed for remote controlled car applications. The SCTX2B/RX2BD have five control keys controlling the motions ( i.e. forward, backward, rightward, leftward, and the turbo function ) of the remote controlled car. Absolute Maximum Ratings DC Supply Voltage-----------------------------0.3V to 5.0V Input/Output Voltage---------------------------GND –0.2V to VDD+0.2V Operating temperature------------------------- -10℃ to 60℃ Storage Temperature---------------- -25℃ to 125℃ Comment* Never allow a stress the values listed under “Absolute Maximum Ratings”, otherwise the device would suffer from a permanent damage. Nor is a stress at the listed value be allowed persist over a period, since an extended exposure to the absolute maximum rating condition may also affect the reliability of the device, if not causing a damage thereof. Oscillation Frequency   SCTX2B VDD=3.0V， Rosc=250K ，Fosc=110KHz~130KHz。 SDRX2BD VDD=3.8V， Rosc=220K ，Fosc=110KHz~130KHz。 Electrical Characteristics SCTX2B（ VDD=4.5V,Fosc=128KHz,TA=25℃ ,unless otherwise specified.） Parameter Operating Voltage Operating Current Stand-by Current DC O/P Driving Current AC O/P Driving Current symbol VDD Idd Istb Idr...
